Chronotype and SJL were derived from the Munich-Chrono-Type-Questionnaire in 320 German students (age 18–25 years) from September 2019 to January 2020, 156 of these participated in an online follow-up survey in June 2020. Body composition was assessed by bioimpedance analysis at baseline. Multivariable linear regression analyses were used to relate chronotype/SJL to body composition; the contribution of self-reported physical activity was tested by mediation analysis. At baseline, a later chronotype and a larger SJL were associated with a higher visceral fat mass (P<0.05), this relation was notably mediated by the attention to physical activity (P<0.05). Chronotype (P = 0.02) but not SJL (P = 0.87) was inversely associated with skeletal muscle mass. During the pandemic lockdown, chronotype hardly changed, but SJL was reduced. Timing and physical activity behaviour remained in most participants and changes were unrelated to chronotype (all P>0.07). A later chronotype/higher SJL may increase the risk of a higher visceral fat mass even in this relatively healthy sample, which may be partly due to their physical activity behaviour. Despite a reduction in SJL during the pandemic lockdown, later chronotypes did not change their physical activity behaviour more than earlier chronotypes.}}, author = {{Krueger, Betina and Stutz, Bianca and Jankovic, Nicole and Alexy, Ute and Kilanowski, Anna and Libuda, Lars and Buyken, Anette E.}}, issn = {{1932-6203}}, journal = {{PLOS ONE}}, keywords = {{Multidisciplinary}}, number = {{1}}, publisher = {{Public Library of Science (PLoS)}}, title = {{{The association of chronotype and social jet lag with body composition in German students: The role of physical activity behaviour and the impact of the pandemic lockdown}}}, doi = {{10.1371/journal.pone.0279620}}, volume = {{18}}, year = {{2023}}, } @article{41456, abstract = {{Abstract Background The German total diet study (TDS)—BfR MEAL Study—established its food list in 2016 based on food consumption data of children (0.5–<5 years) and adults (14–80 years). The list consists of 356 foods selected for analysis in order to ensure ≥90% coverage of the diet. Recently, new food consumption data for children (0.5–<6 and 6–<12 years) in Germany became available, which raised the opportunity to evaluate the applicability of the MEAL food list 2016 on new data. Objective We tested the hypotheses that the MEAL food list 2016 also covers ≥90% of the diet of the new collected food consumption data, and that the selection of foods from younger children and adults was sufficient to also cover the middle age group (6–<12 years). Strategies for updating the existing food list were assessed. Methods Three approaches evaluated the reusability and potential adjustment strategies of the existing food list. Approach 1 applied the existing food list to new food consumption data. Approach 2 allowed the extension of the existing food list to improve coverage of food consumption. Approach 3 set up a new food list based on the new data. Results The MEAL food list 2016 covered 94% of the overall diet of the new collected food consumption data. The diet of the middle age group was sufficiently covered with 91%. However, coverage on main food group or population subgroup level was <90% in some cases. Approach 3 most accurately identified relevant modifications to the existing food list. 94% of the MEAL food list 2016 could be re-used and 51 new foods were identified as potentially relevant. Significance The results suggest that a high investment in the coverage of a TDS food list will lower the effort and the resources to keep data updated in the long-term. Impact There is no established approach to update a TDS food list. This study provides comparative approaches to handle newly collected food consumption data for follow-on TDS activities. The results provide useful information for institutions planning or updating a TDS. Furthermore, new food consumption data for children in Germany recently became available and are here presented for the first time. }}, author = {{Kolbaum, Anna Elena and Ptok, Sebastian and Jung, Christian and Libuda, Lars and Lindtner, Oliver}}, issn = {{1559-0631}}, journal = {{Journal of Exposure Science & Environmental Epidemiology}}, keywords = {{Public Health, Environmental and Occupational Health, Pollution, Toxicology, Epidemiology}}, publisher = {{Springer Science and Business Media LLC}}, title = {{{Reusability of Germany´s total diet study food list upon availability of new food consumption data—comparison of three update strategies}}}, doi = {{10.1038/s41370-023-00522-4}}, year = {{2023}}, } @inproceedings{31849, author = {{Hoffmann, Max and Biehler, Rolf}}, booktitle = {{Proceedings of the Fourth Conference of the International Network for Didactic Research in University Mathematics (INDRUM 2022, 19-22 October 2022)}}, editor = {{Trigueros, Marı́a and Barquero, Berta and Hochmuth, Reinhard and Peters, Jana}}, keywords = {{Teaching and learning of specific topics in university mathematics, Transition to, across and from university mathematics, Student Teachers, Geometry, Congruence, Double Discontinuity.}}, publisher = {{University of Hannover and INDRUM.}}, title = {{{Student Teachers ’ Knowledge of Congruence before a University Course on Geometry}}}, year = {{2023}}, } @inproceedings{43097, author = {{Florensa, Ignasio and Hoffmann, Max and Romo Vázquez, Avenilde and Zandieh, Michelle and Martínez-Planell, Rafael}}, booktitle = {{Proceedings of the Fourth Conference of the International Network for Didactic Research in University Mathematics (INDRUM 2022, 19-22 October 2022)}}, editor = {{Trigueros, Marı́a and Barquero, Berta and Hochmuth, Reinhard and Peters, Jana}}, title = {{{Innovations in university teaching based on mathematic education research}}}, year = {{2023}}, } @inproceedings{43044, abstract = {{Abstract. The combination of incremental sheet metal forming and high-speed forming offers new possibilities for flexible forming processes in the production of large sheet metal components of increased complexity with relatively low forming energies. In this paper, the general feasibility and process differences between the pulse-driven high-speed forming technologies of electrohydraulic and electromagnetic forming were investigated. An example component made of EN AW 6016 aluminum sheet metal was thus formed incrementally by both processes and the forming result evaluated by an optical 3D measurement system. For this purpose, a forming strategy for electromagnetic incremental forming (EMIF) was developed, tested and adapted to the electrohydraulic incremental forming process (EHIF). The discharge energy, the tool displacement and the pressure field of the forming zone were determined as relevant parameters for the definition of an adequate tool path strategy. It was found that the EHIF process is less affected by larger distances between the tool and the blank, while this is a critical variable for force application to the component during EMIF. On the other hand, the more uniform pressure distribution of the EMIF process is advantageous for forming large steady component areas. }}, author = {{Holzmüller, Maik and Linnemann, Maik and Homberg, Werner and Psyk, Verena and Kräusel, Verena and Kroos, Janika}}, booktitle = {{Materials Research Proceedings}}, issn = {{2474-395X}}, keywords = {{Incremental Sheet Forming, Aluminium, High-Speed Forming}}, location = {{Nürnberg}}, pages = {{11--18}}, publisher = {{Materials Research Forum LLC}}, title = {{{Proof of concept for incremental sheet metal forming by means of electromagnetic and electrohydraulic high-speed forming}}}, doi = {{10.21741/9781644902417-2}}, volume = {{25}}, year = {{2023}}, } @article{44477, author = {{Küster, Christine and Klünder, Nina and Wagenknecht, Inga}}, issn = {{2626-0913}}, journal = {{Hauswirtschaft und Wissenschaft}}, pages = {{1--12}}, publisher = {{Deutsche Gesellschaft für Hauswirtschaft e.V.}}, title = {{{Haushaltswissenschaft – Eine Diskussionsgrundlage}}}, doi = {{ 10.23782/HUW_09_2023}}, volume = {{71}}, year = {{2023}}, } @book{44524, editor = {{Meier-Gräwe, Uta and Praetorius, Ina and Tecklenburg, Feline}}, isbn = {{9783847425922}}, pages = {{307}}, publisher = {{Verlag Barbara Budrich}}, title = {{{Wirtschaft neu ausrichten.
